Rule of thumb:
- are you making fun or otherwise mocking someone?
- are you doing it for any “bad reason” whatsoever?
- are you doing something that is/was primarily done by others for “bad reasons”, historically?
- are you doing something that other groups started doing as a replacement for something else that they were not allowed to (that you are)?
I’m half asleep so I may have forgotten something but if I didn’t, then answering No to all of those should be the minimum thing you do.
Something in the way of “an apartment key is useless if you can’t get into the building”.
